文摘

The bisferrocene-benzobisimidazole triad behaves as a selective redox and fluorescent chemosensor for HSO₄^{鈥?/sup> and Hg2+ ions, exhibiting an easily detectable signal change in both the redox potential of the ferrocene/ferrocinium redox couple and in the emission band which is red-shifted (螖位 = 10鈥?3 nm) and enhanced in intensity (Chelation Enhanced Fluorescence, CHEF = 486鈥?25) upon complexation with these ions, in EtOH solutions.}
